Flawfinder version 2.0.10, (C) 2001-2019 David A. Wheeler. Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/lcov-1.14/test/lcov_diff/new/prog.c Examining data/lcov-1.14/test/lcov_diff/old/prog.c Examining data/lcov-1.14/example/gauss.h Examining data/lcov-1.14/example/methods/gauss.c Examining data/lcov-1.14/example/methods/iterate.c Examining data/lcov-1.14/example/example.c Examining data/lcov-1.14/example/iterate.h FINAL RESULTS: data/lcov-1.14/example/example.c:37:11: [2] (integer) atoi: Unless checked, the resulting number can exceed the expected range (CWE-190). If source untrusted, check both minimum and maximum, even if the input had no minus sign (large numbers can roll over into negative number; consider saving to an unsigned value if that is intended). start = atoi(argv[1]); data/lcov-1.14/example/example.c:38:9: [2] (integer) atoi: Unless checked, the resulting number can exceed the expected range (CWE-190). If source untrusted, check both minimum and maximum, even if the input had no minus sign (large numbers can roll over into negative number; consider saving to an unsigned value if that is intended). end = atoi(argv[2]); ANALYSIS SUMMARY: Hits = 2 Lines analyzed = 228 in approximately 0.14 seconds (1685 lines/second) Physical Source Lines of Code (SLOC) = 101 Hits@level = [0] 3 [1] 0 [2] 2 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 5 [1+] 2 [2+] 2 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 49.505 [1+] 19.802 [2+] 19.802 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
